JULIUS J. COWELL, OF WVEEDSPORT, NEW YORK.

VISE.

SPECIFICATION forming part of Letters Patent No. 488,600, dated December27, 1892.

Application filed July 15, 1892. Serial No. 440.132. (No model.)

To all whom it may concern.-

Be it known that I, J ULIUS J. CowELL, of Weedsport, in the county ofCayuga, in the State of New York, have invented new and usefulImprovements in Vises, of which the following, taken in connection withthe accompanying drawings, is a full, clear, and exact description.

My invention relates to Vises, and particularly to that-class which arequick acting,

and in which the jaws are parallel, or can be shifted to receive atapered piece; in which a half nut and half screw are used for quickadjustment of the jaws, and which are provided with auxiliary detachablejaws for gripping round or half round bars or pipes.

My object is to produce an universal vise, with parallel jaws adapted tobe shifted out of parallelism, and with auxiliary jaws for holding pipeor rounded bars, and of quick adjustment as to the jaws on account ofhaving a half nut and a half screw, said screw, or said screw and nut,being provided with a beveled entrance for the thread of one into thatof the other; and also having a spring catch for holding the screw outof engagement with the nut.

My invention consists in the several novel features of construction andoperation hereinafter described and which are specifically set forth inthe claims hereunto annexed. It is constructed as follows referencebeing had to the accompanying drawings in which Figure 1, is a sideelevation of the vise complete, with the pipe jaws in position. Fig. 2,is a vertical longitudinal section, omitting the pipe jaws. Fig. 3, isasectional elevation on line :20 0c omitting the pipe jaws (Fig. 1.)Fig. 4, is a like view on line y y,Fig. 1. Fig. 5, is a top plan of thehalf nut. Fig. 6, is an end elevation thereof. Fig. 7, is an elevationof part of the screw enlarged. Fig. 8, is a sectional elevation of partof the screw, the adjusting collar and screw, and the slide carrying theouter jaw. Fig. 9, is a top plan of the body of thevise with the rearjaw removed, showing the semi-circular locking mortise to receive thelike shaped tenon upon the base of said jaw.

A, is the body of the vise, provided with a flange 1, around its lowerend, which fits onto -a base block 2, provided with countersinks 3,

receiving the point of the stop pin 4,provided with a spring 6, wherebythe body is swiveled upon the base, and can. be set at any point andheld there by said pin. This body is provided with the usual horizontalmortise to receive the slide 7, which carries the front jaw 8. It is.also provided with a vertical mortise opening upward into the slide mor-6o tise, and which receives the shank a of the half nut 9. 1 In the topit is also provided with a mortise 10, of the shape of two semi-circlesof unequal radii, adapted to receive the'post 11, and flange 12, uponthe bottom of the rear jaw 13, so that the flange can be turned underthe over hang of the mortise. The rear face of this jaw body is providedwith a central countersink to receive the point of the screw 14, bywhich it is held in parallelism with the outer jaw, when that is setupon the center; and has also a series of lateral concavities orcountersinks like unto and on each side of the one shown in Fig. 2adapted to also receive said screw, and said jaw is held 7 5 in anyposition thereby, as for taper work. And when the rear jaw is soshifted, the front one is shifted to the like or necessary degree oftaper by means of the swivel mounting upon the base block 2.

B, is the half screw, with a square out thread, of ordinary constructionexcept that the ends of the risers of the thread are beveled or scarfedoff; and the threads of the half nut are also beveled off in likemanner, 8 so that in no case can two ends of threads abut against eachother, and quick and sure entrance is provided for the screw threadsinto those of the nut, and closer jaw adjustment is permitted before thethreads are brought into engagement. When the threads are out ofengagement the front jaw and slide are free to move forward and back.

In the rear of the slide through which the screw passes, is a shoulder15, and 16, is a 5 collar upon the screw, slotted longitudinally foradjustment and abutting against said shoulder, and secured in positionby the screw 17, through said slot, whereby all wear upon the screw canbe taken up. The front end of the screw is provided "with a handle 18,through a head which abuts'against the front end of the slide. A springrod 19, is secured in the slide and extends outward to engage with anotch 20, in the screw head (Fig. 4) and is adapted to play verticallyin the slot 21, and to hold the screw in place when it is out ofengagement with said nut.

Each jaw below its working face is provided with a socket 22, adapted toreceive the stems 23, of the sections of the pipe jaws 24 and 25, whichare tubular and of unequal size so that one'can slide into the other, sothat a pipe or rod of any size can be gripped in the notches 26.

What I claim as my invention and desire to secure by Letters Patent is:

1. In a vise the combination with the jaws, of a slide carrying one jaw,and passing through a mortise in the rear jaw, a square threaded halfscrew within the slide, having the ends of its threads beveled off,andahalf nut provided with a shank fitting in a mortise in the body of therear jaw, and having the ends of its threads beveled off.

2. In a vise the combination with thejaws, of a slide carrying one jawand passing through a mortise in the rear jaw, a square threaded halfscrew within the slide, and having the ends of its threads beveled off,a

half nut provided with a shank fitting in a mortise in the body of therear jaw, and having the ends of its threads beveled off, and having aspring secured in the slide and adapted to engage with a groove in saidscrew and hold it out of engagement with said nut.

3. The combination with the rear jaw swiveled upon a body, and a pinadapted to engage with it, said body beingadjustably swivel'ed upon abase, and a front jaw mounted upon a slide passing through a mortise insaid body, a half screw through said slide,

and a half nut mounted in a mortise within JULIUS J. OOWELL. In presenceof HERBERT A. (JARHART, HOWARD P. DENISON.
